Magma Design Automation has introduced the SystemNav, a tool that extends CAD navigation and circuit debug from ICs to stacked die, PCBs and MCMs (multichip modules). The tool integrates multiple, interactive IC and PCB online trace and circuit debugging with CAD navigation. It allows a rapid signal tracing on chips, stacked dies and MCMs and PCBs, says the company. The tool can help in navigating the failure analysis tools to X, Y locations to determine the root cause of the fault. The tool leverages the company's Camelot IC CAD navigation and circuit debug to trace signals between the chip and the board. The framework of the company's tool is both extensible and modular, enabling features and functions including the 3D cross-sectioning and schematic cross mapping. The tool reads PCB and chip layout formats that are loaded from the Camelot database including open artwork system interchange standard, Virtuoso, Gerber, graphic database system II and AutoCAD drawing exchange format and displays them graphically. For every chip on the board, both the tool and Camelot's MaskView can be invoked enabling seamless movement from an intra-die chip view of the layout and netlists using MaskView to a macro view of a signal trace from die to board using the tool, making fault tracing and diagnostics easy, according to the company.
